In projects with limited budgets, how should you choose a cost-effective radar level meter? As commonly used models, the cost-effectiveness of GRD-80G-01 and GRD-80G-02 directly affects project success. This article provides professional comparative analysis from the dimensions of accuracy, stability, and maintenance cost for quality control personnel and project managers, helping you make the optimal decision among many models such as the GUiDEPULS series.

1. Comparison of Core Parameters: Balancing Accuracy and Measuring Range

The GRD-80G-01 radar level meter adopts 26GHz high-frequency microwave technology, with measurement accuracy up to ±3mm, making it suitable for short and medium range scenarios within 20 meters; while the GRD-80G-02 is upgraded to 80GHz millimeter-wave radar, with accuracy improved to ±1mm and the maximum measuring range extended to 50 meters. According to the measured data of Xi'an Shenghongchuang Instrument Co., Ltd., under operating conditions involving strongly corrosive media (such as concentrated sulfuric acid storage tanks), the narrower beam angle of GRD-80G-02 (3° vs 5°) can effectively avoid tank wall interference.

3. Selection Guide for Typical Application Scenarios

For storage tank monitoring in the chemical industry, the explosion-proof certification (ATEX/IECEx) and PTFE sealing material of GRD-80G-02 are better suited to highly corrosive environments; while for liquid sugar storage tanks in the food and beverage industry, the hygienic-grade 316L stainless steel probe of GRD-80G-01 is sufficient to meet the requirements. It is worth noting that the GUiDEPULS60 series performs better in low-temperature liquid oxygen storage scenarios, and its low-temperature resistance of -196℃ serves as a complementary solution to the GRD series.
